What is lightning protection and landing?
Lightning and contact protection are two completely separate systems and serve different purposes, but it is related in the components that make up each system, lightning protection must have contact. Therefore, when it comes to lightning protection, people often gather into the reception system so that there is a name for lightning protection and landing.
Next up is a system installed to eliminate the leakage of electrical and light electrical equipment to protect equipment and users
Meanwhile, the lightning protection system to work must connect to the receiving site. Basically, the ground of the electrical, light and lightning protection systems is the same, they differ only in terms of ground resistance requirements. The resupply resistance of light electricity requires less than 1 Ohm, the power system requires less than 4 Ohm, lightning protection requires less than 10 Ohm, and annually these parameters must be re-measured, in order for the systems to operate efficiently.
The importance of lightning protection and access to the project
About lightning protection system
In this day and age, everything is growing rapidly and dramatically. High-rise buildings grow everywhere, it accidentally becomes a lightning rod every time it thunders. In order to ensure the safety of human life and property is a project, it is necessary to install a lightning protection system for the project. This system is both anti-lightning and horizontal lightning protection, and lightning-proof spreading on the line
Each function is different, the installation of lightning protection system is also different.
Against straight lightning, modern lightning collectors, also known as the pioneering lightning lightning collectors, that is, it actively attracts the charge of lightning flow directly to the ground, minimizing lightning strikes on the building. Due to its preeminent and proactive nature, today most of the works are used, ignoring the classic lightning protection installation that is no longer suitable, slotting, less aesthetic and easily damaged. When damaged, this classic system will become a lightning pile, which is very dangerous for the building if not detected and repaired in time. Because at this time the lightning current hitting the building did not escape to the ground, leading to it directly impacting the building.
Speaking of horizontal lightning protection system, it is also installed copper bars around the building, to lead the lightning flow to the ground. Although there is a lightning rod, and this needle protects in a spherical style shooting down the building, but there are still angles that it does not capture that will be affected by horizontal lightning, lightning of this type is also very intense, it can break walls, columns, Building, causing great consequences.
There is another lightning protection system that very few people notice, which is a lightning protection system spreading. This system prevents lightning impulses from spreading on power lines that power the power supply into the building, it destroys a series of equipment and machinery, in addition to endangering human life.
About the reception system
This system is also very important, whether people are safe in terms of electricity, whether or not the equipment can be used long-term is thanks to this system. Even the lightning protection system, if there is no unscepable contact or reception, the lightning protection system will leave, unusable, on the contrary, causing serious consequences.
Insulections, there is a 3-phase power grid neutrality, a refueling for lightning protection, a power supply and a light power supply. Each system has different requirements and must be independent of each other. In addition, it must also be far from each other, meet the voltage requirements of electricity, avoid lightning pulses of lightning protection systems spreading through the system of electricity and light electricity, and then bounce back on the power system, light electricity.
Lightning resistance: Ground resistance must be less than 10 OHM
Power system respical: Soil renunage must be less than 4 OHM
Light power system insues: Soil renunage must be less than 1 OHM
This is a mandatory requirement, if not achieved, it must be reworked, worked more or treated with chemicals. Otherwise it won't work.
This system is also very small in installation costs, but it brings many outstanding advantages: safety for people, protection of equipment, machinery, protection of project works.
